In music, galant refers to the style which was fashionable from the 1720s to the 1770s. This movement featured a return to simplicity and immediacy of appeal after the complexity of the late Baroque era. This meant simpler, more song-like melodies, decreased use of polyphony, short, periodic phrases, a reduced harmonic vocabulary emphasizing tonic and dominant, and a clear distinction between soloist and accompaniment. C. P. E. Bach and Daniel Gottlob Türk, who were among the most significant theorists of the late 18th century, contrasted the galant with the "learned" or "strict" styles (Bach 1753, passim; Türk 1789, p. 405). The German empfindsamer Stil, which seeks to express personal emotions and sensitivity, can be seen either as a closely related North-German dialect of the international galant style (Heartz and Brown 2001a; Heartz and Brown 2001b; Palmer 2001, xvii; Wolf 2003), or as
contrasted with it, as between the music of Carl Philipp Emmanuel Bach, a founder of both styles, and that of Johann Christian Bach, who carried the galant style further and was closer to classical.[citation needed]

This musical style was part of the wider galant movement in art at the time.

The rejection of so much accumulated learning and formula in music is paralleled only by the rejection in the early 20th century of the entire structure of key relationships. Not every contemporary was delighted with this revolutionary simplification: Johann Samuel Petri, in his Anleitung zur praktischen Musik (1782) spoke of the "great catastrophe in music" (Blume 1970, p. 20).

The change was as much at the birth of Romanticism as it was of Classicism. The folk-song element in poetry, like the singable cantabile melody in galant music, was brought to public notice in Thomas Percy's Reliques of Ancient Poetry (1765) and James Macpherson's "Ossian" inventions during the 1760s.

This simplified style was melody-driven, not constructed, as so much classical music was to be, on rhythmic or melodic motifs: "It is indicative that Haydn, even in his old age, is reported to have said, 'If you want to know whether a melody is really beautiful, sing it without accompaniment'" (Blume 1970, p. 19). This simplification also extended to harmonic rhythm, which is generally slower in galant music than is the case in the earlier baroque style, thus making lavish melodic ornamentation and nuances of secondary harmonic colorings more important (Palmer 2001, xvii).

The affinities of galant style with Rococo in the visual arts are easily overplayed, but characteristics that were valued in both genres were freshness, accessibility and charm. Watteau's fêtes galantes were rococo not merely in subject matter, but also in the lighter, cleaner tonality of his palette, and the glazes that supplied a galant translucency to his finished pictures often compared to the orchestrations of galant music (Heartz 2003,[page needed]).
